CONCRETE-BURIAL-VAULT FORM.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application led February 12, 1913. Serial No. 747,874.

To all whom it may concern.'

Be it known that I, LEON P. DUNN, a citizen of the United States, and a resident of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Concrete- Burial-Vault Forms,of which the following is a specification.

This invention relates to molds for making burial vaults, watering troughs, etc., from concrete and other plastic materials, and has for its object to provide a mold of steel plates and angle iron which may be quickly adjusted in length, width and height, whereby to ermit of the formation o f structures of di erent sizes and dimenslons.

A further object of the invention is to provide a mold including a supporting base. which is adjustable to accommodate the ad-- justed mold sections and in which the base of the burial vault or watering trough may be formed before the mold sections for the walls are placed in position.

Other and further objects of the present invention tending to generally increase the durability and efficiency of the present class of devices will be readily understood from the following description, in which reference is made to the accompanying drawings forming a part of this specification and in which- Figure 1 is a top plan view of the inner and outer mold sections in operative position on the base. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical longitudinal section taken therethrough substantially on the line 3 3 of Fig. 1. Fig. 4 is a vertical transverse sectionv taken therethrough on the line 4 4 of Fig. 2. Fig. 5 is a detail horizontal section through one corner of the outer mold section, taken substantially on the line 5--5 of Fig. 2. Fig. 6 is a plan view of one corner of the inner meld section. Fig. 7 is a detail perspective view of v one of the locking pins and its key. Fig. 8

is a vertical cross section through a complete burial vault which may be formed by means of my improved mold, and Fig. 9 is a plan view of the supporting base, the corner portions thereof being broken away an in section.

Referring now to these gures, and more particularly to Fig. 9, the supporting base consists of a substantially rectangular frame -composed of angle bars A, each of which flanged apertured end of the respective adjacent bar and adapted'to be located therethrough by means of a key as. The several angle bars A may thus be adjusted in order that the frame which they form may be increased or decreased in size in accordance with the adjustment of the upper mold parts to be hereinafter described, the angle bars being provided with vertical apertures a by which the outer mold may be secured thereto.

The outer mold as may be clearly seen from Figs. 1 to l inclusive, consists of four sides B, each of which is provided with an angle bar 6 extending along its lower edge and apertured to receive locking pins for connecting the same upon the angle bars A of the base mold, and each of said sides B further including an upper section comprising longitudinal plates 6', 62 and 6-8 which are rigidly and permanently connected by braces 64 and a lower section comprising longitudinal plates 65. 66. 61 and 68 which are secured together by means of transverse braces 69. These longitudinal plates are preferably braced by means of small longitudinal angle bars 610 riveted or bolted thereto and the upper section of each side of the mold is provided with transverse members 611 which may be bolted by bolts 612 to the braces 69 whereby to connect the upper and lower sections of each side, itl being understood that the said transverse braces 611 are provided with a plurality of apertures as particularly illustrated inFig. 4 in order that the two sections of each of the mold sides may be adjusted with respect to one another. Thus if the height of the mold is to be decreased, one of the strips, for instance the strip 65, of the lower section of each of the mold sides is unbolted and removed and the bolts 612 may then be 'removed and the upper section moved down so as to rest on the plate 6B and again connected by the bolts 612 through another aperture in each of the transverse braces 611.

vertical angle bar B2, in several sections cor- 'responding to the several plates and aperwardly extending spacing arms C adaptedto engage the outer surface ofthe upper portion of the inner mold, and also arms C which are rovided at their inner ends with clips C2 or engagement over the upper edges of the inner mold.

The inner mold comprises sides D each of which consists of a series of vertical plates which are removably connected by inner longitudinal angle bars D having a series of apertures adjacent their contiguous ends whereby they may be adjustably connected to one another by bolts al, in this manner providing for the removal or addition of one or more plates whereby to shorten or lengthen the sides as desired.

The inner mold is braced in operative position as indicated in Fig. 1 by means 'of the adjustable transverse braces D2 and diagonal corner braces D3, each of the sides D having a curved corner 'piece hinged thereto at one end so as to occupy the space between the respective end thereof and the end of the adjacent side, these corner pieces being in 4dicated at DL and being engageable by latches al. Thus when it is desired to mold a burial vault such as indicated at E in Fig. 8, the base mold shown in Fig. 9 is assembled in desired adjustment upon a pallet F and cement leveled therein, after which the 'inner and outer mold sections are disposed and connected in position particularly as indicated in- Fig. 4 and cement is poured between the same in order toform the sides c of the vault.

From the foregoing description of the outer mold, it will be readily understood that the same may be selectively adjusted as to height without necessitating similar adjustment of the inner mold, both molds further being correspondingly adjusted where the vault is of special length or width. The

top ey of the burial vault is formed within a mold of suitable construction, to fit upon the body thereof as shown in Fig. 8, and thus j' complete the yvault for use.

In Fig. 7, I have shown a locking pin H provided with a transverse aperture l1. through which the key I may extend, the pin thus shown being preferred for use in detachably connecting the sides of the base and outer molds as previously described.

I claim:

1. The combination of an inner form or mold and an adjustable outer mold comprising four sides, each of said sideshaving at one end means whereby to adjustably connect the same to an adjacent side and each of said sides comprising an upper and a lower section, one of which sections embodies a plurality of independent `plates which may be removed and added to, and adjustable connections between the said sec- \tions and each of the independent plates of the latter section.

2. The combination of a base mold embodying an adjustable frame, an adjustable outer mold connected to and supported by said base mold and comprising sides having a plurality of -longitudinal plates and adjustable connections between the said plates, each of the plates having an angle bar at one end and a series of apertures adjacent its opposite end and locking pins carried by the said angle bars and adapted for engagement through selected apertures.

3. The combination of abase mold embodying an adjustable frame, an adjustable outer mold connected to and supported by said base mold and comprising sides each having horizontal plates forming upper and lower sections of which the lower sections are provided with adjustable connections between their plates whereby the latter may be removed or added to, adjustable connections vbetween the sections of each side, the said longitudinal plates being each provided with an angle bar at one end and series of apertures at their opposite ends, and locking pins carried by the angle bars and adapted for engagement through selected apertures.

4. The combination of a base mold comprising angle bars having adjustable connections at their ends whereby to form a frame, an adjustable outer mold having r angle bars secured along the lower edges of its sides and adapted for connection with the angle bars of the base mold, angle bars also extending along the upper edges of the sides of the outer mold, an inner mold or form disposed within the outer mold and spacing arms having connection with the upper angle bars of the outer mold sides and extending into contact with the sides of the inner mold, certain of which arms are provided with clips whereby to engage over the upper edges of the sides of the inner mold for the purpose described.
